There is a special form of a quadratic that is best for graphing the equation. We'll analyze it thoroughly here. Here y0 is the y coordinate of the vertex, x0 is the x coordinate of the vertex, and a is the amplitude, a measure of the thickness of the parabola.
Comments: Comments Off. According to the U.S. Geological Survey the average person uses between 80-100 gallons of water per day and estimates that 95% of the water we use, goes down the drain (1). So we waste 76-95 gallons per day. A shower, for example, uses between 2-5 gallons per minute.A dishwasher uses between 4-10 gallons of water for each load. A washing machine uses between 25-40 gallons of water every time we do a load of laundry.With just the use of basic water-using appliances, we use a lot of water. shower, for example, uses between 2-5 gallons per minute. A dishwasher uses between 4-10 gallons of water for each load. A washing machine uses between 25-40 gallons of water every time we do a load of laundry.
Since 1985 total daily water usage has remained consistent between 399-410 BGD. This is despite a population that has grown from 237 million in 1985 to 297 million in 2005. Water conservation is making a difference. In 1980 the US used 1.980 gallons of water per person every day; in 2005 that number had dropped to 1,383.
